Removing a target from the list.
If you mark a target and fail to kill the target or target the wrong mob, you can remove the target from the list, by selecting any target, pressing and holding the Mark Target (Press & Hold) key, and right-clicking on the raid icon already assigned to the wrong target.
However, you should be able to target a new mob with the same icon... so might be a bug there. Try the right click to deselect for a start and see if that helps. Let me know if you still can't re-mark with an existing marked icon.
